The use of auxiliary diagnostic tools such as computed tomography is a manifestation of
the technological advances that distinguish current society and within which dentistry
has also undergone a scientific and technological evolution. The images that are part of
the dentomaxillofacial massif can be detected through the use of Cone Beam computed
tomography, capable of reproducing three-dimensional images with a high degree of
resolution and without superimposing neighboring anatomical structures, which is the
advantage of these with regard to the use of periapical radiography, which have been
used conventionally for a long time in endodontic practice. Objective: To determine the
prevalence of single rooted incisors with two canals through Cone Beam. Materials
and methods: To this end, an observational cross-sectional study was carried out, based
on a study sample represented by 120 tomographies performed at the Xplora Deim
Radiological Center in the city of Quito. The data were then collected and processed in
the SPSS statistical program, applying the statistical Chi-square test. Results: We
corroborated the existence of 5 incisors with two root canals, which had the I, II and V
configuration according to Vertucci from the Cone Beam tomography. Conclusions:
There is a prevalence of single rooted lower incisors with two canals in the female
gender, with a predominance of single rooted incisors with two canals in the group of
19 to 30 years of age, the morphology of the lower incisor canal was classified with a
predominance of the group II and V according to Vertucci
